Biotic: Living things in the
ecosystem
Bio: Life
Tic: Factor
*Dead things are still biotic
because they were once living.
Abiotic: Not a living thing
A: Not
Biotic: Life factor
*Non-living things can’t be dead
because they were not alive to begin with
Producer: Make new energy (food)
for our ecosystem (against the system) (maker)
Pro: For or positive
Consumer: Use/ Take away energy
Con: Against or negative
PRODUCERS = AUTOTROPHS
Autotrophs: Makes their own food
(Food from inside)
Auto:
Self
Troph:
Energy/Nutrition
CONSUMER = HETEROTROPH
Heterotroph: Get their food from
different (other) sources (Food from Outside)
Hetero:
Different (Other Sources)
Troph:
Energy/Nutrition
Ecosystem: How all things interact
together
Eco: Life
System: how things interact
Producer: Make energy (food) for
our ecosystem (against the system)
Pro: For or positive
Consumer: Use/ Take away energy
Con: Against or negative
Decompose: To breakdown what was
made
De: Breakdown
Compose: Make
Decomposer: Break down leftover energy found in
dead things. (Eats dead things)
Organism: Any living things having
1- infinity (any number) of cells.
You must have one cell, any living things, no
matter how big or small
· Small Organism: Bacteria,
Germ
· Medium Organism: Bug
· Large Organism: Dog,
Human
Species: Group of the same kinds
of organisms
Interactions: Things that happen
between plants and/or animals
Inter: Between
Actions: How plants and animals do
things
Guiding
Question:
How do species interactions lead to changes in
organisms?
PREDATOR/PREY
+ -
·
Predator
·
Prey
·
Reduce
|
Must hunt for food, Predator = Lion
Who is hunted, Prey = Zebra
·
Predators eat prey and reduce their numbers
(prey are killed so there are less zebra now)
Go down in number
This relationship is good for the predator
because they get nutrition, but is bad for the prey because they die.
+ - Positive for one and bad for the other
|
PARASITISM
+ -
Ectoparasite
Endoparasite
|
Relationship where one organism needs a host to
survive. Takes nutrients from the host.
EXAMPLE:
Mistletoe, heartworms, Fleas, ticks
Ecto:
Outside
Ectoderm (Skin)
Endo:
Inside
Endoscopy
+ - Good for one and bad for the other
|
Mutualism + +
Three Types of Mutual
Relationships:
Energetic and Nutritional
Protective
Transport
|
Two
plants or animals that live and work together. It is good for both plants/animals.
(They work well together)
EXAMPLE: Hammerhead Shark and
Smaller fish
Smaller
fish eat the bad parasite off of shark
+
+ Because it is positive (good) for both involved.
Transfer
of energy/nutrients from one organism to another.
Defense
against predators or herbivores. One animal
The
movement of seeds, pollen, or adult organisms.
|
Commensalism + /
|
A
relationship with two animals. One host and one secondary animal (symbiont).
The host does not get hurt or helped and the secondary animal is helped. The
Symbiont is helped because they get food, housing, and/or transportation.
EXAMPLE:
Hippo and the bird
+
/ Good for one but does not help or harm the other.
Common: Same
Mensa: Table or together
Ism: turns my verb into an
adjective (action)
|
Ecosystem
Interactions
Habitat
|
Area
where an organism lives.
|
Niche
|
A
job an organism has inside its environment.
|
Competition
|
Occurs
when more than one organism uses a resource at one time.
